Thank you for purchasing the Mitsubishi Electric MELSEC iQ-R series programmable controllers.
This manual describes the functions, parameter settings, and troubleshooting of the relevant products listed below.
Before using this product, please read this manual and the relevant manuals carefully and develop familiarity with the
functions and performance of the MELSEC iQ-R series programmable controller to handle the product correctly.
When applying the program examples provided in this manual to an actual system, ensure the applicability and confirm that it
will not cause system control problems.
Please make sure that the end users read this manual.
Unless otherwise specified, this manual provides program examples in which the I/O numbers of X/Y0 to X/YF
are assigned to the A/D converter module. Assign I/O numbers when applying the program examples to an
actual system. For I/O number assignment, refer to the following.

Modes
Modes of the R60AD8-G are roughly classified into two groups listed below. A mode is set using the module parameter of GX
Works3. Mode transition is not possible while the module is operating.
Mode
Standard mode
SIL2 mode
Note that the R60AD16-G does not support SIL2 mode and operates only in standard mode.
■Enabling/disabling the safety module
To operate the R60AD8-G in SIL2 mode, it is necessary to enable the safety module so that the set parameters become
enabled.
To stop the safety I/O of the R60AD8-G operating in SIL2 mode, or to use that module in standard mode in the other system,
disabling the safety module is required.

Description
• The mode for using the A/D converter module in a normal system
• The standard mode is subdivided into three types: normal mode, offset/gain
setting mode, and Q compatible mode.
• The mode is certified according to the safety requirements of IEC61508:
2010 SIL2 and IEC61511: 2015 SIL2. This mode is used when a customer
builds a SIL2 system using products compliant with IEC61508: 2010 SIL2 or
IEC61511: 2015 SIL2.
• The R60AD8-G in SIL2 mode can be used to build safety functions for
general industry machinery.
